"No-one on the Colony believes in Macra! There is no such thing as Macra! Macra do not exist! There are no Macra!!"

Well maybe stop going on about them so much then?

He's right though. This colony is lovely - except for the brainwashing, harrowing jingles, cheerless cheerleading, occupational hazards and the ministrations of hit security group, Ola and the Bootboys, that is.

Oh and the Macra, of course. Not that there are any Macra. Or are there...?

Well, yes there are, as the name of the story implies, and they're a crabby (and shouty) bunch of crustaceans, with their grubby pincers on the reins of power within the colony. Meanwhile, Ben goes over to the dark side, Polly gets a haircut, Jamie has a fling and the Doctor has a problem with excess gas.

But did Jim and Martin give The Macra Terror 11 out of 10? Or did it just wash over their brains?
